Now, do you have any idea why you have not sold your townhouse? If it is not being shown while other townhouses in the complex are selling, you almost certainly have a pricing issue. If it is being shown, have you gotten feedback from the potential buyers? Is it possible, while being super updated, there are condition or presentation problems with the unit? On my website, in the science and art of staging, I offer a lot of advice about preparing a property for sale. Feel free to explore there.
Personally if I could, I would never sell. Accumulate rental properties as retirement income.
